[0002] In the prior art, when star wheels are selectively transported, a fixed guardrail design is basically adopted in the triangular area at the intersection. Based on the selection of the bottle in the channel path, the binding force is derived from the negative pressure vacuum of the hollow pipe of the star wheel, and a closed negative pressure area is formed on the outer wall of the bottle, so that the bottle follows the star wheel to rotate into the predetermined channel. Based on this physical phenomenon, the following state between the bottle and the star wheel is realized by the judgment of the sensor and the state control of the vacuum pipeline, so as to achieve the purpose of screening the bottle into different tracks.

[0025] Example

[0026] like Figures 1-4As shown, the present invention provides an explosion-proof bottle mechanism at the junction of star wheels, including star wheel 1, star wheel 2, and a two-degree-of-freedom elastic mechanism 3, which are assembled from the above components.

[0027] This invention employs a near-two-degree-of-freedom elastic mechanism 3 at the junction of the two star wheels. This elastic mechanism consists of a movable guardrail (movable block 4), a connecting block 7, a telescopic guide rod, a guide sleeve, a compression spring, a rotating movable block 12, a base plate, a tension spring, and a tail plate 15. Under the action of the compression and tension springs, the movable block 4, mounted on this mechanism, simultaneously possesses two degrees of freedom—planar rotation and telescopic extension—within a certain range when subjected to external force, exhibiting good flexibility and quickly returning to its initial state after the external force disappears.

[0028] This invention comprises a star wheel 1, a star wheel 2, and a near-two-degree-of-freedom elastic mechanism 3. A movable block 4 is installed within the elastic mechanism, forming two distinct channel regions, channel 5 and channel 6, with the star wheel 1 and star wheel 2, respectively. The near-two-degree-of-freedom elastic mechanism 3 contains a connecting block 7, on which telescopic guide rods 8 and 9 are fixed. Furthermore, telescopic guide rods 8 and 9 slide relative to each other within guide sleeves 10 and 11, respectively, while guide sleeves 10 and 11 are mounted within a rotating movable block 12. The rotating movable block 12 contains compression springs 13 and 14. One end of each compression spring 13 and 14 contacts the tail of each telescopic guide rod 8 and 9, respectively. Finally, a tail plate 15 seals the compression springs 13 and 14 within the rotating movable block 12, preventing them from detaching. A further rotating movable block 12 is installed on the pin 17 on the base plate 16, and the rotating movable block 12 can rotate around the pin 17. In addition, a horizontally arranged tension spring 18 and tension spring 29 are provided below the rotating movable block 12. One end of tension spring 18 is connected to the column 20 on the rotating movable block 12, and the other end of tension spring 18 is connected to the column 22 on the base plate 16. At the same time, one end of tension spring 21 is connected to the column 21 on the rotating movable block 12, and the other end of tension spring 219 is connected to the column 23 on the base plate 16.

[0029] Under normal conditions, when Star Wheel 1 transports bottle 24 to the junction with Star Wheel 2, the vacuum state of control pipe 1 25 and control pipe 2 26 is controlled to achieve the target selection purpose of bottle 24 following.

[0030] When bottle 24 breaks free from the vacuum adsorption of the star wheel during its movement, it cannot properly enter the predetermined channel. Under the pressure of the star wheel or subsequent bottles, it comes into contact with the guardrail movable block 4. At this point, the flexible action of the spring mechanism 3 increases the width of channel one 5 or channel two 6, ultimately allowing bottle 24 to be smoothly delivered, thus preventing it from bursting. This also provides clearance for a small number of bottles that haven't fully entered the channel, giving bottle 24 sufficient time and space to enter the designated channel and avoiding the risk of breakage. This improves operational stability and safety; enhances efficiency and quality; and the invention is simple, reliable, and durable.
